5 Claims.

Generically this invention relates to boat bailers but more especially it is directed to such a means for selectively ejecting water from and injecting water into a boat while the boat is in motion.

A primary object of this invention is the provision of a portable device of this character readily attachable to and removable from, in the present instance, a small boat and readily operable during the movement of the boat to withdraw bilge water or the like therefrom and/or inject water therein as desired.

Another object-0f this invention is the provision of a bai-ler of this character more especially adapted for mounting on the stern of a small boat without interference with an out-board motor or other type of propeller means and readily operable by the operator in the boat, during movement of the boat, to remove water from the interior thereof, or to inject water therein.

A further object of this invention is the provision of a portable bailer of this character having a conduit section and a flexible hose in connection with its upper end adapted to extend within and to the bottom of the boat, and a scoop-like formation at said sections outer and lower submerged end, having valve means operable therein, its construction being such that the operation of said valve to one position direct-s the water from the scoop upwardly through the conduit and said flexible hose, and operation in the opposite direction cuts oil the flow from said scoop formation to said vertical conduit and at the same time projects a bafile element below said conduit, whereby the water passing through the scoop is deflected downwardly forming a pocket and vacuum at the lower or bilge water discharge end which withdraws the water from the boat through the flexible connection and vertical conduit, and the flow of which is controllable by the speed of the boat.

A still further object of this invention is the provision of a caller of this character having a water receiving element or scoop and valve structure at its submerged end operable to inject water into the boat or eject water from the boat during forward motion of said boat, the formation of which structure and the action of the valve being such as to prevent the gathering or depositing of refuse, sea weed and the like in the area of the device occupied in discharging the bilge water from the boat.

With these and other objects in view, which will become apparent as the description proceeds, the invention resides in the construction, combine:

The bailers or devices of this character for disposing of bilge water from boats, with which I am familiar, have proven deficient in many respects, especially for use in connection with the smaller type of boat, such as bailer structures of a permanent nature requiring a reservation of a part of the interior area of the boat for installation of its component parts, and the type having long sections of hose trailing in rear of the boat free at its extremity and being flexible, following an irregular forward course beyond control of the operator, with tendency to sway from "side to side and lift out of the water if the speed of the boat is substantial, and designed at or near the point of discharge with a constricted member or members causing by such design an accumulation of seaweed or other refuse, thereby rendering the device inoperative. "Therefore, it was to overcome such disadvantages that I designed the device forming the subject matter of this invention, comprising a subs-tantially L-shaped conduit body portion, having means for attaching said portion eX-teriorly of a boat, preferably the stern. Sal-d L-porticn at the lower normally submerged end of said conduit being substantially in the form of a hollow open mouth scoop element tapering rearwardly and forming a restricted throat portion in communication with the vertical body portion, the bottom of said element being formed with an elongated opening extending to and including the lower end of said vertical portion, an elongated valve member of a length substantially corresponding to that of said bottom is connected to an operating handle means mounted on the upper curved end of said conduit member and to the free end of the conduit member is attached a flexible hose portion extending to the bottom .of said boat. Said valve is hingedly mounted in said scoop in a manner such that the operation .of said .handle in one direction elevates the rear end of the valve and lowers the front portion into seating engagement with said bottom, closing the opening in the latter and positioning said valve in water injecting position (Fig. 2) Operation of said handle in the opposite direction raises the forward end of the valve into engagement with the upper edge of said mouth, as shown in Fig. 3, closing the throat of said scoop and directing the water through said bottom opening during the movement of said boat, as shown in Fig. and effecting withdrawal of the bilge water and its discharge from the lower end of said conduit body portion, as will be well understood.

In the illustrated embodiment characterizing this invention there is shown a boat A and a portable bailer device B adapted to be detachably mounted thereon operable, when the boat is in forward motion, to eject bilge water or the like from the interior of the boat or inject water therein, as desired.

The bailer device B comprises a tubular normally vertical conduit section 9 curved inwardly at its upper end as at 2 and to which is suitably connected as at 3 a flexible hose section 5 of a suitable length to extend downwardly to the bottom of the boat. Said device B is removably attachable, in the present instance, to the stern of the boat by the finger clips 5 welded or otherwise secured to the surface of conduit section 5 and insertible in anchor members suitably sccured to the stern of the boat as at 6.

The lower normally submerged end l of conduit l is integrally formed with a forwardly extending hollow right-angle triangular scoop element 8 with its longer side constituting the upstanding ears i5 providing on the upper side a trough-like space it for a purpose directly more fully appearing. An operating rod i? is connected to the rear end of said valve intermediate said ears l5 as at E8 and the upper end of said rod is connected as at 59 to one end of a manually operable handle '28 mounted on a cotter-pin 2i or the like, extending through the fork or yokeshaped member 22 integrally formed on or otherwise suitably attached to the curved portion 2 as at 23.

Said valve 14 is pivotly mounted in said scoop 8 on cotter-pin 24 or the like at a point approximately one-third of the length of the valve i l from its rear end in a manner such that the downward movement of the handle 26 raises the rear end of the valve, closing the bottom opening [3 and simultaneously lowering the front end to seat on bottom 9, closing the opening I2 and placing said valve in water injecting position. The upward movement of handle 20 causes the forward portion of valve I to move upward and seat against the upper edge of the mouth opening l0 and at the same time closing the throat II and lowering the rear trough portion 6 to open the lower end l3 of conduit 1 and positioning the valve in bilge water ejecting position. The Water entering mouth I6 and passing through bottom opening I2 is deflected downwardly by the undersurface of the troughportion l6 which acts as a bafile, thereby increasing the pocket and vacuum formation at the rear of discharge opening 13 and which accelerates the withdrawal of the bilge water from the boat. The force of the water passing through openings l0 and I2 maintains the valve M in water ejecting position until the manual movement of operating handle 20 moves said valve to water injecting position, as in the first instance.

It will be noted that the particular construction and'operative arrangement of the scoop 8 and valve I4 is such, that when valve is in water injecting position the entire opening I2 is closed and operation of the valve to water ejecting position divides said opening 12 into two separate openings for the independent passage therethrough of water from two distinct sources.

From the above it will be apparent that I have provided a portable bailer of the character removably attachable exteriorly of a boat, having a valve controlled scoop-like means at its lower end, and a flexible hose means connected to its upper end, means operable by the operator of the boat from his seat therein for controlling said valve during the movement of the boat to initially prime the device by directing sufficient water therethrough to fill the device, and then said valve may be instantly operated to cut off the flow of water through said scoop to said device and direct it through the bottom of said scoop to remove the bilge or other water from the boat. Also, if desired, the device may be operated as previously described to direct water through said hose in a manner to flush out the boat to effect cleaning thereof, said device being likewise adaptable to act as a fire hose in case of fire, the force or the stream of water for such purpose, or any purpose, being controlled by the speed of the boat. The body of the device adapted to be constructed of copper, galvanized iron pipe, aluminum, plastic or other suitable material, and the device being of a size and weight rendering it easily attached to and removed from the boat, yet adapted to occupy a small space, comprising few parts, simple in construction, manufacturable at a minimum cost, and efficient for the purposes intended.

Although in practice I have found that the form of my invention illustrated in the accompanying drawings and referred to in the above description as the preferred embodiment, is most eflicient and practical, yet realizing that conditions concurrent with the adoption of my invention will necessarily vary, I desire to emphasize that various changes in details of construction, proportion and arrangement of parts, may

be resorted to within the scope of the appended claims without departing from or sacrificing any of the principles of this invention.
